Circumference solve for r
WebJan 11, 2024 · volume = (4/3) × π × r³. Usually, you don't know the radius - but you can measure the circumference of the sphere instead, e.g., using the string or rope. The sphere circumference is the one-dimensional distance around the sphere at its widest point. circumference = 2 × π × r, so: r = circumference / (2 × π) Webwe have the value of A thus we can solve for r and find its value . πr 2 = A r 2 = A π r = A π = 16 πin 2 π = 16 in 2 = 4 in . and has circumference L = 2 πr. substitute r and find L. L = 2 πr = 2 π × 4 in = 8 πin
